Ensaios de campo e plataformas de fenotipagem

A análise genética (mapeamento QTL) e a análise ecofisiológica foram realizadas com base em grandes bases de dados recolhidas de ensaios de campo e de plataforma. As experiências de campo visavam determinar a resposta de rendimento dos painéis SolACE a variações na disponibilidade de recursos. Plataformas de fenotipagem e experiências em condições controladas destinadas a recolher dados sobre a arquitectura de raiz e a resposta microbiológica a imitações combinadas de recursos.

Uma vasta gama de genótipos de trigo foi testada em quatro ensaios de campo sob controlo e condições de stress combinadas. 250 genótipos de trigo panificável foram testados em ensaios de campo em Levroux, França e Gréoux-les-Bains, França. Outros 250 genótipos do trigo duro foram testados em ensaios de campo em Foggia, Itália e Mauguio, França. Além disso, os grandes painéis de diversidade foram fenotípicos a nível da raiz em ensaios de plataforma de fenotipagem em Lovaina, Bélgica e Dijon, França.

Numa segunda fase, 80 genótipos seleccionados (40 de trigo panificável e 40 de trigo duro) foram seleccionados para serem analisados em maior detalhe em ensaios de campo semi-controlados em Gréoux-les-Bains e Clermont, França e Copenhaga, Dinamarca, bem como numa plataforma de fenotipagem em Montpellier, França.

Para além dos ensaios de pão e trigo duro, 24 variedades de batata estavam também a ser testadas numa plataforma de estufa de batata em Dundee, Scottland.

A informação genética destes ensaios em grande escala e orientados foram combinados num quadro de modelização que associa modelos de plantas estruturais funcionais (FSPM) e modelos de culturas, a fim de melhorar a nossa compreensão do desempenho das culturas sob limitações.

The Roots of Agriculture: A series on below-ground research from the SolACE project

The SolACE project proudly present a series on root phenotyping and below-ground traits as explored through our research.

The series includes three parts:

1. Too Deep or Not Too Deep: Deep-rooting – 20 January, 2022

We will look at deep-rooting, including modelling, to consider how a vertical approach contributes to this field, including a virtual look at the Radimax KU facility used in the SolACE project and contributions from Matthias Wissuwa of the Japan International Research Center for Agricultural Sciences.

Lead organiser: Kristian Thorup-Kristensen, University of Copenhagen

2. To Dig or Not To Dig: Root phenotyping for breeding – 10 February, 2022

This event will cover root phenotyping strategies and tools that are within the reach of breeding, with a particular attention to the value and limitations of field and controlled conditions phenotyping. It will include contributions from the SolACE project and benefit from the long experience and vision of Jonathan Lynch (Penn State University).

Lead organiser: Xavier Draye, Université catholique de Louvain (UCL)

3. To Interact or Not to Interact: The Root Microbiome – 3 March, 2022

This event will decipher the expectation for a better understanding of plant and microbiome interactions, including tools and methods for root phenotyping and characterization of structural or functional traits associated with plant-microbiome-soil interactions. Laurent Philippot of INRAE will provide an opening presentation, followed by examples from SolACE project trials of bio-stimulants and a virtual tour of a platform (4PMI) devoted to this topic.

Lead organiser: Christophe Salon, French National Research Institute for Agriculture, Food and the Environment (INRAE)


Two additional stakeholder events are also being organised, looking at different outcomes from the SolACE project. These will all feed into the final SolACE stakeholder event, which is being held in Brussels, Belgium on 12 April, 2022.
